Abstract: A method and apparatus for supporting routing area (RA) update in a long term evolution (LTE) general packet radio service (GPRS) tunneling protocol (GTP)-based system are disclosed. A wireless transmit/receive unit (WTRU) sends an RA update request to a new evolved Node-B (eNodeB) and a mobility management entity (MME). The MME sends an update packet data protocol (PDP) context request to an access gateway (AGW), whereby a new tunnel is established between the new eNodeB and the AGW. For an inter-MME routing area update, the WTRU sends an RA update request to a new eNodeB and a new MME. The new MME sends an MME context request to an AGW. The AGW sends an MME context response to the new MME. The new MME sends an update PDP context request to the AGW, whereby a new tunnel is established between the new eNodeB and the AGW.

Abstract: A method and apparatus for implementing a handoff between radio access networks (RANs)(110a) deployed under different radio access technologies (RATs) are disclosed. A wireless transmit/receive unit (WTRU) (150) is equipped with at least two radio units to support the RATs. Each RAN sends a list of co-located RANs in the coverage area of the RAN to the WTRU. The WTRU stores the list and determines whether handoff criteria is met by one of the co-located RANs. The WTRU then initiates a handoff from a current RAN to a target RAN if the handoff criteria is met by the target RAN (110a). Alternatively, the WTRU may send a measurement report to the current RAN, whereby the current RAN determines whether handoff criteria is met by a selected one of the co-located RANs and initiate a handoff to the selected RAN if the handoff criteria is met.

Abstract: A method and system for supporting an evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) are disclosed. The system includes a wireless transmit/receive unit (WTRU), a UTRAN and an E-UTRAN. The UTRAN sends to the WTRU a list of available radio access technologies in a coverage area of the UTRAN. The list includes information related to the E-UTRAN. The WTRU receives the list and may initiate a handoff based on the list. The WTRU then sends its multi-mode/multi- RAT capability information including the E-UTRAN capability to the UTRAN. The UTRAN then sends a measurement capability message to the WTRU. The measurement capability message includes parameters necessary for performing measurements on an E-UTRAN channel. The WTRU performs measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to the E-UTRAN based on the measurement results.

Abstract: Method and apparatus for delivering voice/data services within a piconet operating over a limited range or over a WLAN (1803) communicating with 3GPP devices by reformatting data into IP format before delivering to the WLAN (1803). The service is Short Message Service (SMS) (102). Upon receipt of the SMS message, relevant routing information is retrieved. A PDGW (1805) address for the SMS message is identified and sent to the PDGW address which identifies the WLAN use equipment (UE) (1801) for receiving the SMS and reformats the SMS message into IP format for delivery to the UE. A protocol architecture is provided for SMS delivery over WLANs, in particular, for UMTS/CDMA based SMS over WLAN (1803) through two alternative mechanisms: SMS tunneling and SMS proxy, for protocols for the delivery of SMS across the WLAN (1803).

Abstract: A method and system for reporting short message (SM) capability over an IP multimedia subsystem (IMS) using a session initiation protocol (SIP) are disclosed. A wireless transmit/receive unit (WTRU) registers with a core network and sends a message indicating its SM capability via the IMS to the core network. The core network then updates the WTRU capabilities based on the message and routes an SM to the WTRU (fig.1, 130) via the IMS (fig.1, 116).

Abstract: A method for delivering a short message service (SMS) message to an interworking wireless local area network user equipment (UE) (122) begins by registering the UE with an Internet Protocol short message gateway (IP- SM-GW) (118). A capability report is sent from the UE to the IP-SM-GW, the capability report including the capabilities of the UE. A SMS message is transmitted from a short message service center (SMSC) (104) to the IP-SM-GW. The capabilities of the UE are evaluated at the IP-SM-GW to determine whether the UE can receive the SMS message, and the SMS message is delivered to the UE via the IP-SM-GW if the UE has the capabilities to receive the SMS message.
